Trigger, action, and data mapping
Submit one test response before you build the action - you cannot map fields you have never seen.
PROCEDURE: Create scenario > module Google Forms > Watch Responses > choose the form (Form ID) > submit a test response > Run once to see the output bundle. Add Google Sheets > Add a Row > spreadsheet by ID > sheet 'Sheet1'. Mapping: drag from the Forms output into each column - first name via text answers > answers > value; same for last name, email, message, budget; set unused columns to false. Submit a second response; confirm the row.
The trigger-plus-action proof that every automation is built on.
